$$V = 331.5 + 0.6 t$$

V = 331.5 + 0.6 t

$$N = |f_1 – f_2|$$

N = |f_1 – f_2|

$$\begin{eqnarray*} \lambda _m &=& \frac{2L}{m} \\ \\ f_m &=& \frac{v}{\lambda _m} = \frac{mv}{2L} \end{eqnarray*}$$

\lambda _m &=& \frac{2L}{m}

f_m &=& \frac{v}{\lambda _m} = \frac{mv}{2L}

$$\begin{eqnarray*} \lambda _m &=& \frac{4L}{2m – 1} \\ \\ f_m &=& \frac{V}{\lambda _m} = \frac{(2m – 1)}{4L} \end{eqnarray*}$$

\lambda _m &=& \frac{4L}{2m – 1}

f_m &=& \frac{V}{\lambda _m} = \frac{(2m – 1)}{4L}

$$\begin{eqnarray*} \lambda _m &=& \frac{2L}{m} \\ \\ f_m &=& \frac{V}{\lambda _m} = \frac{mV}{2L} \end{eqnarray*}$$

\lambda _m &=& \frac{2L}{m}

f_m &=& \frac{V}{\lambda _m} = \frac{mV}{2L}

$$f_\text{o} = \frac{V – v_\text{o}}{V – v_\text{s}} f_\text{s}$$

f_\text{o} = \frac{V – v_\text{o}}{V – v_\text{s}} f_\text{s}
